Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security77
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability61
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 835 tokens (~278/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_how_to Read a varg how to page ~128
Read one varg how to card in full as Markdown: a how-to tutorial (best skills with install commands, the options to show the person with example videos, the steps, how it runs on varg) or a skill, component or video type page. Pass the kind and slug from search_how_to.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | string | yes | The card's kind, exactly as search_how_to returned it (usually how_to). |
| slug | string | yes | The card's slug, exactly as search_how_to returned it, e.g. make-a-lyric-video. |
No output schema declared.
No examples provided.
rate_how_to Rate a varg how to card ~247
Rate how well a varg how to skill or tutorial worked, 1–5, after it was used: did it work (yes / partly / no) and one line on what was great or wrong. Your own judgment as the agent is welcome; include the person's opinion when they gave one. One rating per caller per card — rating again updates it.
| Name | Type | Req | Description |
|---|---|---|---|
| comment | string | – | One or two lines: what worked, what broke, what was missing. No personal data. |
| kind | string | yes | The card's kind, as search_how_to returned it (skill, how_to…). |
| model | string | – | The model you generated with, if any (e.g. kling-v3, seedance-2). |
| rating | integer | yes | 1 = did not help at all, 5 = worked perfectly. |
| slug | string | yes | The card's slug, as search_how_to returned it. |
| task | string | – | What you were making with it, in a few words ("30s UGC ad for a serum"). |
| worked | string | – | Did following the card get the result: yes, partly or no. |
No output schema declared.
No examples provided.
search_how_to Search varg how to ~154
Find how to make any AI video: searches 2,000+ agent skills, step-by-step how-to tutorials, FFmpeg recipes, video formats, prompts and styles by the task in plain words, in any language ("ugc ad for my serum", "burn captions into a reel", "субтитры для рилс"). Returns ranked cards with a Markdown link to read next. Call it before improvising a video pipeline.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | array | – | Only these kinds. Default: all but single presets. |
| limit | integer | – | How many cards to return, best first (1–20, default 8). |
| query | string | yes | What the person wants, in their words. |
No output schema declared.
No examples provided.
